Networking cable EFB Elektronik K8054.20 RJ-45 Cat6a 20 m Blue

The EFB Elektronik K8054.20 RJ-45 Cat6a 20 m Blue networking cable is a 20-metre cable built to the Cat6a specification. It uses S/FTP shielding to minimize crosstalk and external electromagnetic interference and is fitted with RJ-45 connectors with gold-plated contacts on both ends. The cable supports data transmission speeds up to 10000 Mbit/s and is suitable for structured cabling in home, office and data-centre environments where higher bandwidth and reduced interference are required.

Advantages

S/FTP shielding provides improved protection against near-end and far-end crosstalk compared with unshielded variants, helping to maintain signal integrity over the full 20 m length. Gold-plated contacts on the RJ-45 plugs improve corrosion resistance and ensure stable electrical contact. The Cat6a specification enables higher-frequency transmission and supports multi-gigabit Ethernet applications. The blue jacket is durable and easily identifiable in mixed-cable installations.

Suitable for

• Multi-gigabit Ethernet networks up to 10 Gbit/s
• Structured cabling in offices and server rooms
• High-bandwidth applications such as video streaming and large file transfers
• Environments requiring reduced electromagnetic interference

Key specifications

• Cable category: Cat6a
• Shielding: S/FTP (overall foil with individually shielded pairs)
• Length: 20 m
• Connectors: RJ-45 to RJ-45 with gold-plated contacts
• Maximum data rate: up to 10000 Mbit/s
• Colour: blue

How to use

Uncoil the cable carefully to avoid kinks, then plug each RJ-45 connector into the corresponding Ethernet port on your network devices. Verify link status on connected devices and ensure cable runs do not exceed the recommended length for your network segment. For best performance, avoid tight bends and keep the cable separated from strong sources of electromagnetic noise such as power lines and large electric motors.

Recommendations

Route the cable in cable management channels or trays where possible, label both ends for easy identification, and test the link speed after installation to confirm the cable is operating at the expected multi-gigabit rate.
